MACHINE FOR SPLITTING DOUBLE PlLED FABRICS.

SPECIFICATION forming part of Letters Patent No. 417,915, dated December 24, 1889. Application filed October 9, 1888. Serial No. 287,641. (No model.)

`To @ZZ whom it may concern.-

Be it known that we, EDWIN R. HANDY and THOMAS H. HANDY, of Manville, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Machines for Splitting Double Pile Fabrics, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to an improvenient in machines for cutting .or separating such fabrics as have been woven double, with two close surfaces and with an intermediate pile, as velvet, velveteen, and velvet carpet, and is an improvement on United States Patgranted August 23, 1887, to

- Russell Handy.

To the above purpose our invention consists in the certain novel construction and combination of the several different features, as hereinafter fully described and claimed.

In the accompanying drawings illustrating our invention, Figure 1 is a sectional view of our improved machine. Fig. 2 is a top View of our improved machine. Fig. 3 is a sectional view taken on the line 3 3 of Fig. 1. j

In the said drawings like numbers of reference designate corresponding parts throughout.

Referring to the drawings, 4 designates the main driving-shaft, which is supported in the in the direction of the axis of the shaft.

ported between the vertical ribs or guides 16 n 16, formed on or secured to the side frames 17 17. At each end of the shaft 14 is rigidly secured, to turn therewith, the screw 18, which passes through the nut 19, attached to each of the side frames 17, each screw being provided with the hand-wheel 20, so that by turning one of the hand-Wheels the cams will be moved' to one side or the other, thereby lifting or lowering the bed-plate 13 and securing an accurate vertical adjustment. The arched piece 21 is movably mounted on the bed-plate 13 in the V-shaped grooves 22, and is provided with the boss 23, which is screw-thread ed, and through which the' screw 24 passes. This screw 24 is supported in the upright bearing-piece 25, which forms part of the bedplate 13, and to the outer or free end of the screw 24 is attached the worm-gear 26..

Supported in the two bearings 27 27, for1ning part of or attached to the bed-plate 13, is

Athe cross-shaft 28, which is provided at each end with the hand-wheels 29 29, and at the center of this shaft 28 is formed a worm 30, which intermeshes with the worm-gear 26, so that upon one of the hand-wheels 29 being turned the wornrgear 26 will be revolved and with it the screw 24, thereby moving the arched piece 21 toward or away from the circular knife or cutter 12. The arched piece 21 can be accurately adjusted to the cylindrical knife l2 to guide the double pile fabric to the knife byv which the same is to be split or cut into two sheets. By reason of the horizontal adjustment of the arch-piece 21 toward' the knife 12 a cutting contact between the knife and the pile is at all timesinsured, and as the edge of the knife wears away, by reason. 0f the action of the grinders on the same and the cutting of the pile, the arch-piece 21 is moved toward the knife, thereby insuring a perfect division of the fabric.

On the cross-plate 31 are mounted in suitable guides the two bearing-slides 32 and 33, for supporting the shafts 34 and 35,@on the ends of which are secured the grindingf wheels and the pulleys 36 and 37, which receive power through the elastic belts 318 and 39, which pass over the double pulley 40, mounted on the main' shaft 4, and by which the shaft and grinding-wheels are revolved.

' on the shaft 53.

' to the hub 61.

At the outer ends of the bearing-slides 32 and 33 are the bosses or clips 41 and 42, to which one end of each of the screws 43 and 44 is secured. These screws are provided With the hand-Wheels 45 and 46, and pass through holes in the side frames, Which are screw-threaded to fit them, so that upon one of the hand- Wheels being turned the corresponding grinding-Wheel will be adjusted to bear against the inner or outer face of the circular knife sufficient to grind the same and maintain an efficient cutting-edge.

The power-shaft 47, provided with the pulley 50, is supported in suitable bearings d-irectly beneath the main shaft- 4, which is provided with the pulley 49 and is connected to the power-shaft by the belt 48. At the opposite end of the power-shaft to that carrying the pulley 50 is attached the worm 51, which intermeshes with the Worm-gear 52, mounted On this shaft 53 are mounted the pulley 54 inside the frame and the sprocklet-gear 55 on the outside of the frame.'

The take-up rolls 56, 57, and 58 are sup,- ported in suitable bearings formed in or attached to the side frames 17 17, the shaft of the roll 57 passing through the frame and being supplied with the sprocket-gear 59, for receiving power through the chain 60, which passes over the sprocket-gear 55. The sprocket-gear 59 has the beveled hub 61, and is loosely mounted on the reduced end of the shaft of the roll 57; also loosely mounted on the reduced end of the same shaft is the handwheel 62, which has a hub 63 to correspond The end of the shaft is pro.- vided with the nut 64, for securely holding the hand-Wheel and sprocket in position. As the sprocket-gear is continuously driven, carrying With it the hand-Wheel, upon the hand- Wheel being held the two beveled hubs Will actpto force the hand-Wheel against the nut4 64 and away from the sprocket-gear, which will be forced against the shoulder formed by reducing the shaft, and the shaft, carrying with it the roll, Will be caused to revolve and take up the lower split fabric. The take-up for the' upper split fabric on the opposite end of the machine consists of but a single roll 65, and as there is no pull necessary to this part of the fabric this roll 65 receives its power through the belt 66, which passes over the pulley 54, attached to and revolving with the shaft 53, thence under the pulley 67, up

'over the pulley 68, down under the pulley 69.',

and back to the pulley 54.

The rolls 65, 70, and 71 are formed on the y same circle as the circular knife or cutter12, thereby keeping the fabric in approximately the same arc of the circle as the knife and facilitating the guiding of the fabric to and from the cutting-knife. i

7 2 is 'the beam upon which the double pile fabric is Wound as it is Woven in the loom.

" This beam is' supported on a shaft 73, jour naled in grooves formed in the side frames.

The operation of the machine is asfollows: A strip of plain cloth, of sufficient length to reach from the arch 2l -to beyond the griprolls 56, 57, and 58, is iirst secured to the end of the under half of the double pile fabric. The beam is then placed in position, the cloth being passed up over the roll 71, then over and through the arch, then over roll and y through the grip or take-up rolls 56, 57, and

58. When now power is supplied, the circular knife will be caused to revolve at a high rate of speed, and the arch having been properly adj usted the fabricwill be split. The upper half being' held by hand until sufficient length to overlap the roll 65 has been cut, Which roll will thereafter take up. the slack, the lower half will pass under the arch over the roll 70 to the grip or take-up rolls 5.6, 57 and 58, which will grip and pull the cloth up against the cutting-edge of the circular knife at a uniform rate of speed and tension. As the cutting-edge of the knife becomes dull, either one or both of the grinding-Wheels can be brought to bear on the same by turning the hand-wheel 45 or 46, or the grinders may be kept continuously in contact with the knife, thereby at all times insuring a sharp edge during the running of the machine.

Having thus described our invention, We claim as new and desire to secure by Letters Patent- 1. In a machine for splitting pile fabric, the combination, with the cylindrical knife and actuating means therefor, of; all @relied guide provided With an adjusting-screw for moving the said arched guide toward and from the knife, a support on which the arched guide rests and on which it can be moved to adjust the same horizontally, andthe camsy mounted on a horizontal shaft'provided with adjusting-screws for adjusting'said Support vertically, as described. j
